Since for α>2 and β>2 the beta distribution is (symmetric or unsymmetric) bell shaped, it follows that the Fisher information matrix is positive-definite only for bell-shaped ...
In probability theory and statistics, the beta distribution is a family of continuous probability distributions defined on the interval [0, 1] in terms of two positive parameters, denoted by alpha (α) and beta (β), that appear as exponents of the variable and its complement to 1, respectively, and control the … See more Probability density function The probability density function (PDF) of the beta distribution, for 0 ≤ x ≤ 1, and shape parameters α, β > 0, is a power function of the variable x and of its reflection (1 … See more Transformations • If X ~ Beta(α, β) then 1 − X ~ Beta(β, α) mirror-image symmetry • If X ~ Beta(α, β) then $${\displaystyle {\tfrac {X}{1-X}}\sim {\beta '}(\alpha ,\beta )}$$. The beta prime distribution, also called "beta distribution of the second kind". See more Order statistics The beta distribution has an important application in the theory of order statistics. A basic result is that the distribution of the kth smallest of a sample of size n from a continuous uniform distribution has a beta distribution.
